Arctic Sea ice and atmospheric circulation anomalies since 1954
The relationship between Arctic sea ice concentration anomalies, particularly those associated with the "Great Salinity Anomaly" of 1968-1982, and atmospheric circulation anomalies is investigated. Empirical orthogonal function (EOF) analyses are performed on winter and summer sea ice conc...

The relationship between Arctic sea ice concentration anomalies, particularly those associated with the "Great Salinity Anomaly" of 1968-1982, and atmospheric circulation anomalies is investigated. Empirical orthogonal function (EOF) analyses are performed on winter and summer sea ice concentrations, sea-level pressure, 500 hPa heights and 850 hPa temperatures: these data cover the Northern Hemisphere north of 45$ sp circ$N during the post-World War II era. Spatial maps of temporal correlation coefficients between EOF 1 of winter sea ice concentration and the atmospheric anomaly fields are calculated. Significant correlations (at 95 and 99% levels) were found to exist between EOF 1 of winter sea ice and the atmospheric anomaly fields at zero lag, and with ice leading by one and one-and-a-half years, and ice lagging by one year. The main emphasis of the thesis is to identify connections between Arctic sea ice and atmospheric circulation anomalies at interannual timescales. |
